The gamified mHealth arm also showed eight-week between-group improvements of 0.54 kg in skeletal muscle, 0.46 percentage points in body-fat reduction, 6.5 seconds in run time and 2 points in depressive-symptom reduction, while body weight and BMI differences were not significant.
What this does not establish
Selected short-term secondary changes are not clinical remission, durable mental-health benefit, weight-loss efficacy or effects of gamification alone.
Counterevidence & uncertainty
Diet and sleep were not systematically controlled; multiple secondary outcomes raise multiplicity concerns.
What would change the reading
Update with corrected multiplicity, objective replication and follow-up after incentives stop.
